small random number,

[beansandsausages]

hey, i am trying to make a small random number, ie 0.045 etc ...

 

code i am currently using is:

 

$number = rand(0.000,0.999); 

 

it only ever returns the value 0, is there a dirrent function to use?

This is because rand() returns a random integer.  If you want you could probably take that integer and divide it by 10 x the length of the integer returned by rand()?  Hope this helps.

The rand() function returns integers.

 

You want to do something like:

<?php
$r = rand(0,999)/1000;
echo number_format($r,3);
?>
